ROTARY GAS-SCRUBBER.

SPECIFICATION forming part of Letters Patent No. 444,300, dated January6, 1891.

Application iiled July 12,1890. Serial No. 358,492. (No model.)

To @ZZ whom it may concern:

-Be it known that I, WILLIAM MooNEY, of North Plainfield, in the-countyof Somerset and State of New Jersey, have invented a new and usefulRotary Gas-Scrubber, of

which the following is a full, clear, and exact description.

This invention relates to improvements in gas-scrubbers of the rotarytype wherein the gas is introduced and made to impinge on wet surfacesto remove impurities.

My invention further consists inthe construction and combination ofparts, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a portionof this specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure l is a side elevation, partly sectional, of the scrubber, showingone division or compartment of the casing provided with dashersrevolubly mounted upon a center shaft. Fig. 2 is a partly-sectionalplan' view taken on the line 2 2 in Fig. 3. Fig. 3 is a transversesection with the dashers removed, taken on the line 3 3 in Fig. 2. Fig.4 is a longitudinal section'of one gas-compartment in the scrubberenlarged, taken on the line 4 4 in Fig. 5. Fig. 5 is a transversesectional elevation of one segmental portion of a washer-compartment inthe scrubber; and Fig. 6 is an enlarged broken sectional view of twodashers and spindles between the dashers, showing the relative positionof the spindles with regard to the perforations in the dashers.

The outer casing of the scrubber, as shown, consists of a rectangulartankA and a coversection A', having side wings or extensions C, whichextend along the sides, which wings are connected by a segmental top orcover e. The casing is divided by transverse partitions g intoequal-sized compartments D, the partitions extending across the wings Cand being provided in the wings with openings p at alternate ends nearlythe size of the crosssection ot' the wing. At diagonally-oppositecorners of the casing the wings are provided, respectively, with aninlet and an outlet opening F and G.

As shown, the casing consists of a baseplate, to which are secured theend pieces g and the sectional side pieces g2, provided with sideflanges d2, a marginal flange c extending around the upper edges of theend and side pieces, these parts forming the body of the tank A. Thepartitions g are secured to the base-plate and between the flanges a2,and in marginal contour conform to the cross-section of the completedcasing. Upper end pieces g3 complete the ends. Angle or L-shaped pieces6o d', provided with flanges c2, rest on the tlange c of the side piecesg2 between the partitions g and between the partitions and end pieces.Segmental cover-plates e., flanged and united at e2 and provided withstraight end portions 65 e', rest on the upper flanged ends of theanglepieces c between the partitions g, the whole being secured togetherin any suitable manner; but the casing may be constructed in anyapproved manner.

A shaft B,supported in brackets d, secured to the ends of the casing,extends longitudinally of the casing about centrally thereof, passingthrough stuffing-boxes a ine the casing ends to preventpthe leakage ofgas, and -7 5 through thimbles d3 in the partitions g. The shaft isprovided at one end with a drivingpulley B. On the shaft B between thepartitions are xed hubs h, having polygonal rims h', which each supporttwo parallel 8o spaced disks close to the partitions g, which disks areprovided on their inner sides with radial ribs t', the pair of disks ineach compartment forming a hollow wheel fitting closely in thecompartment and adapted to revolve therein.

The hollow wheels support segmental scrubhing-frames I, consisting ofsegmental side plates t2, adapted to fit between the ribs t", and ofperforated flasher-plates m, preferably 90 of Wood, parallelly arrangedand extending between the plates i2 at right angles therewith, as shown.The .perforations m of the dashers m are arranged in spaced rows, andbetween the dashers aligning the perforations therein are arranged rowsof spindles n, held in the plates 112, so that currents of gas passingthrough the perforations m will impinge upon the spindles and. bedivided, as shown in Fig. 6. A

At a proper point, preferably on one end of the casing, is a water-inletpipe H, said pipe IOO being bent to produce a trap to prevent escape ofgas, and at the opposite end, at a point aligning the bottoms of theopenings p in the partitions g, is a trapped outlet-pipe I', by whichlocation of the outlet the tank A will be kept full of water.

The shaft B, with the wheels carrying the scrubbing-frames, beingrevolved, gas entering the scrubber through the inlet-pipe F traversesthe first compartment D through the revolving wheel in lthe direction ofthe arrow y. It then passes through the opening p in the first partitioninto the second compartment D, passing through the wheel in saidcompartment in the direction of the arrow ywhence the gas passes throughthe remaining compartments in the direction of the arrows l, 2, and 3.

The gas in its passage through the perforations of the dashers ot' thescrubbing-frames.

and against the4 spindles, which are all kept wet by their immersion asthe Wheels revolve in the water in the tank A, will be thoroughlypurified, and as the peripheries of the. wheels closely t the top orcover of the casing the gas is compelled to pass through thescrubhing-frames.

By the frictional contact of the gas with the wet scrubbers tarry matternot previously7 taken out will be mechanically removed, and atthe sametime any ammonia and carbonio acid remaining in the gas will be taken upby the water.

From the peculiarconstruction an d arrangement of this device it isapparent that alarge frictional area is afforded tor impinging contactof the gas, as the gas enters and passes, through the revolvingscrubbers at right angles to their axis of revolution.

While it is preferred to use the spindles n, they may be dispensed with,and an increased number of dashers m be used with good results. I

Having th us described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In agas-scrubber, ascrubbing-frame consisting of two parallel-spacedsegmental plates i2, a series of transverse parallel foraminated platesm, and a series of rods or spindles between each pair of foraminatedplates and in line with the opposing perforations m m therein, as shownand described.

2. A gas-scrubbing machine consisting of the tank A, having a curved topA', opposite longitudinaliy-extending side wings or eXtensonsC,transverse partitions g,confo1;m ing in marginal contour to a transversesection through said tank, top, and wings and having openings, p atalternate ends Within` said wings or extensions, inlet F and outlet G, alongitudinal shaft B, and scrubbingwheels. on the said shaft, one forevery compartment, and each consisting of two circular plates t' t',having radial ribs t" t, segmental frames seated between plates 'L' onsaid ribs and formed of parallel segmental plates, i?, transverseparallel foraminated plates m,y connecting the plates t2, and rods orspindles n, between the foraminated plates and in line with theiropposed apertures, the said wheels fitting closely the sides and curvedtop of the several compartment-s, substantially as set forth.
